' IMPROVEMENT lIn 'PLoUeua TO ALL PERSONS TO WHOM THESE PRESENTS MAYCOME:

Beit known that I, ELBRIDGE G. MATTHEWS, of South Natick, in the countyofMiddlesex, and Sta'te ot Massachusetts, have inventedA a new anduseful Improvement in Ploughs, and do hereby declare the same tobe fullydescribed iu the following specification, and represented in theaecompanyng drawings, of which- Figure 1 is a side elevation, I

Figure 2 a top'view,

Figure 3 a. rear end elevation, and

Figure 4 a longitudinall section of a plough-standard provided with myinvention.

Figure 5 is a perspective view of a plough to which my inventionappertains.

In such drawings, S denotes what is termed the plough-standard. From therear part ofthe face a of the standard I extend upward and curvebackward, in manner as exhibited iu the drawings, an arm, A.Apianged onits opposite sides, as shown at I) b t b. This arm is to sustain the twohandles of the plough, which are to be laid against-opposite sides ofthe arm, and between and` against its ilanges, and are to be bolted tothe arm. Furthermore, the arm is to give support to the beam, and is tohave an odset or shelf, c, projecting'from it, for a support-or stay tothe rear end of the same, and in rear of the said shelf there is to bea. h ole, d, .made down through the arm. Both the standard and the shelfare to be provided with projections or studs e e, to enter theplough-'beam when laid on the shelf` and top of the standard.' vThesestuds -prevent laterai movement or" the beam on'its supports. The beam,when resting on them, is bolted to the top of thestandard. It is alsosecured down upon the shelf cby a bolt going through the beam and thehole d of the armi The `base part, a, of the standard provide with ashoe,'B, which I fasten thereto `by means of screw-bolts and nuts, thesame being arranged as represented at 7i It in iig. 4. The shoe Bembraces opposite s-ides of the standard, and is provided with atooth,f, to enter the standard or abut against a buttress, g, arrangedthereon, in manner as shown in iig. 4. The said tooth and buttress serveto' prevent the back strain on the shoe fromv breaking the bolts bywhchithe shoe is confined tothe base of the standard. v

I am aware that a plough-standard has heretofore been made with a shortarm below the beam, and to give support to one of the handles oftheplough, therefore, I do not claim such. l My arm A extends upward, soas `to support both handles and the plough-beam. |ln=srefore-l 'l 1. Iclaim the arrangement of the arm A, its angesand shelf` e, or theirequivalents, with the ploughstandards S, and its base a, as described.

2. I also claim the arrangement of the tooth f and the buttress g withthe plough-standard and i'ts shoe, as set forth.

' 3. I also claim the plough-standard as made with an arm to extend backand up from its base, so as to give support to the two handles and thebeam, substantially as set forthA ELBRIDGE G. MATTHEWS.
